The structure and working principle of the rolling riveting device for installing and fixing the joint bearing are further described below through examples:

As shown in Fig. 1, Fig. 3 and Fig. 4, the rolling riveting device for installing and fixing joint bearings mainly includes rolling riveting head I1, adjusting column I2, pushing bracket 3, rolling riveting head II8, roller 9, thrust bearing I11, roller Riveting roller 12, needle roller bearing 13, thrust bearing II 14, spring 15, transverse shaft 16 and adjustment column II 17. Rolling riveting head I1 and adjusting column I2 are welded together, the axis of rolling riveting head I1 coincides with the axis of adjusting column I2, and the length of adjusting column I2 is 2/3 of the thickness of joint bearing. Rolling riveting head II8 is welded together with adjusting column II17, the axis of rolling riveting head II8 coincides with the axis of adjusting column II17, and the length of adjusting column II17 is 1/3 of the thickness of joint bearing. The adjusting surface of the adjusting column I2 of the rolling riveting head I1 is the same as that of the adjusting column II17 of the rolling riveting head II8. Roller riveting head I1 and roller riveting head II8 each have three evenly distributed roller mounting grooves 18 and three evenly distributed roller mounting grooves 19. Roller riveting head I1 and roller riveting head II8 have the same structure.
